Motor for vacuum cleaner

Abstract

A motor for vacuum cleaner is composed of casing, end covers, stator, rotor, shaft, blade wheel and its cover, stator terminal, and electric brush and its terminals for contacting with stator terminal. Its feature is that said electric brush has 3 contact parts with stator terminal, so having high contact reliability.

Description

technical field [0001] The invention belongs to motors, in particular to motors for vacuum cleaners. Background technique [0002] Refer below figure 1 , Figure 2a and Figure 2b , a prior art motor for a vacuum cleaner will be described. figure 1 It is a simple structural diagram of a motor for a vacuum cleaner in the prior art, Figure 2a and Figure 2b is during the contact between the stator terminals and the brush terminals figure 1 Enlarged view of part "A", Figure 2a When the brush 31 is inserted from the outer surface of the motor case 110 inward, the stator terminal 14 just contacts the brush terminal 32, Figure 2b This is the case when the brush 31 is fully inserted. [0003] Such as figure 1 As shown, on the inner side of the motor housing 110, the stator 120 with the stator terminal 14 is forcibly installed, and the rotor 135 is pressed into the rotor 135 with the motor shaft 131, and the rotor 135 is located inside the stator 120. The motor cover 11...

AI Technical Summary

Problems solved by technology

[0005] like Figure 2a and Figure 2b The shown prior art vacuum cleaner motor has the disadvantage that when the brush 31 is inserted from the outside to the inside of the motor housing 110, the free end portion of the stator terminal 14 is excessively pushed toward the bent portion 32a of the brush terminal 32, cause the brush terminal 32 to deform

Therefore, poor contact between the stator terminal 14 and the brush terminal 32 occurs, and the motor cannot be started.
